Greetings, I just got back the results from my third oil analysis from AVLAB here in the US. The analysis is supposed to compare with other Jabiru engines of similar time on them. I don't think they have other Jabirus in their database as they offer no comparisons. That's where you guys come in. All three analysis for my 3300 came back as normal except for Iron which was around 180ppm +or-10. All oil changes were around 35hrs. Allthough they could not compare values with a similar engine, they did comment that the Iron reading "seemed high" on all three samples. They did note that this may be because of the break in cycle. Can anyone comment on their experience with oil analysis, especially with regard to Iron wear during the first 100hrs? Are these normal Iron figures for Jabiru engines during the first 100hrs? I cut and pasted the results and comments below. Without engines to compare with elevated Iron numbers have little meaning. Thanks for your responses.

Comments: IRON SEEMS HIGH. HIGH VALUES AND INCREASES ARE NOT UNCOMMON DURING THE ENGINE BREAK-IN CYCLE. ALL OTHER OIL VALUES SEEM FINE FOR THE ENGINE BREAK-IN CYCLE. WE WILL CONTINUE TO MONITOR THIS ENGINE WITH YOUR NEXT SAMPLE. PLEASE CONTACT THE ENGINE MANUFACTURER'S SERVICE REP IF FURTHER ASSISTANCE IS NEEDED.

Hi Peter, thanks for your reply. Your 300 hour sample was not much less than mine. Having a baseline with which to compare really helps. Hopefully the iron figure will go down over time. I got my metal check kit from Amazon here in the US. https://smile.amazon.com/Aviation-Labor ... alysis+kit Hope this helps Jeff
